COPYING APPARATUS. i

Specication of Letters Patent.

To all who-m 'it may concern:

Be it known that I, GUsTAvn H. CoQnEUG- NIOT, a citizen ofthe UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented a certain new and useful Improvement inCopyino' Apparatus, of which the following is a specification.

My invention relates to a duplicating apparatus, and particularly to aphotographic copying machine for making true copies of papers, `picturesand the like, directly on Paperv One of the objects of this invention isto provide an apparatus in which the paper is exposed, developed andfixed, in consecutive operations, without Anecessitating manual handlingof the paper.

Another obj ect of this invention is to provide an apparatus in whichthe paper after development is automatically removed from the developingcylinder and delivered facel z part of said casing 1, and in ana-xialline down to the fixing bath.

^ With these and other objects in View', this I inventionconsists of thefeatures, details of construction and combination of parts described inconnection with the accompany-f ing drawings and then more particularlyipointed out in the claims.y

` In the drawings, Figure 1, is a side eleva- 3 tion, partly in section,showing the photop graphing apparat-us, the feed roll for the1 paper,and the developing cylinder. Fig. 2,1

1s a section on lines 2-2, Fig. 1, looking in the direction of thearrow, and showing the developing cylinder, mechanism for clamping thepaper. Fig. 3,

and vactuating is a fragmentary section on lines Ji- 3, Fig.t 2, showinthe operating mechanism for thel release o the paper from the developingcylinder; Fig. 4, is a segregated,.perspecg tive view, showing theoperating mechanismi for the clamping and releasing of the paper,

themeans for removing the paper from the; cylinder, and lvthe operatingmeans for they removing means. Fig. 5, is a side eleva-l tion'sliowingthe position of the pa er re moving means, when the paper is c amped' onthe cylinder. Fi 6, is a similar view showin the paper c amped in thecylinder and he d clamped during development, and Fig. ,7, is a sideelevation showing the operative position of the means for removing thepaper from the cylinder, and in dotted:

lines, the position of the clamping vmeans for the paper, after therelease of the same. Referring to the drawings, 1, designates aPatentedOct. 8, 1912. y Application filed .Tune 2451912; Serial No.705,660.

casing, in the upper part of which is jourp naled a flanged roller 2,for a roll of sensitizedpaper 3, arranged to be fed to the exposurechamber 4, of said casing, provided with photographic bellows 5, andlens 6, by rollers 7. In said exposure chamber 4,

are two spaced plates 8, and 9, .the former being an ordinarytransparent glass plate, While the latter vis a ground glass plate onwhich the focus of the object from the lens .is made. These plates 8,and 9, serve also l to guide the paper through the opening 1 0,

in Said yexposure chamber 4, and to bring-the end 11, of t-hepaper inproper position for Yclamping and developing, by means presentlydescribed, after the same has been sheared off, by a preferably rotaryknife 12, disposed on the top of said casing 1, and below said feedingrollers 7 In the lower tegral with said casing, and having its other endextending through a sleeve 16, which is journaled in a bearing 17,integral with said casing. Said cylinder 13, is provided with alongitudinal groove 18, in which is disposed an oscillable bar 19,mounted in plates 20 and 21, secured to the ends of said cylinder. Saidbar is provided with lugs 22, which, when the bar 19, is oscillated,clamp the end of the paper against the wall 23, of said longitudinalgroove 18, and hold said paper clamped during the revolution by a crank24, pinned on said shaft 14, of said cylinder, in a developing solutionin a tray 25, supported in proper relation to said cylinder. The saidwall 23, of the groove 18, is provided with projections 26, formingsupports for the end of the paper, to prevent it from sliding under thecla-nip bar 19. On one end of said clamp bar' 19, is fixed an arin 27,clearly shown in Fig. 4, provided with a pin 2S, disposed in a cam slot29, of a disk 30, which is integral with said sleeve 16. Connected withsaid sleeve 16, which is i loosely mounted on said shaft 14, and located`011 the outside of said casing 1, i-s a knurled nut 31, by means ofwhich the sleeve 16, and

consequently the disk 3Q, is oscillated relasition substantial-lyv asshown in said tively to the said shaft and cylinder, to control theopening and" closing movement of said clamp bar 19. 'llhe crank V24,*isheld rigid during the movement of said nut 31, byv any suitable means,as,` a bifurcation 32, hingedly secured to the casing 1. As seen in Fig.4, the clamp bar 19, has been oscillated to bring thev lugs '22, away.from the wall 23.of the groove 18, in the cylinder4 1, the pin'28, onthe arm 27, occupying the pore. When the disk 30, is oscillated in thed1rection of the arrow, Fig. 4, the cam slot 29,

will cause an oscillation ofsaid clarnp barA 19,' which thereupon.clampsI the end of the paper inthe cylinder 13,"the position of theparts then being-substantially as shown in Fig. 5. Th' disk 30 andcylinder 13, are now connected, and the crank operated to revolve thecylinder, with the paper thereon in the developing solution in the tray25.

When the cylinder has been revolved 'for a sufficient length oftimetodevelop the paper, the clamp bar`19, is operated to release thevendv of they paper, whichvis then delivered face down to the fixingsolution in the tray 32, fitting in the bottom of said casing. rlhis isaccomplished bythe following mechanism: Loosely mounted in a rabbet ofsaid bearing 17, is, a disk 33, providedl in thevpe- 'riphery' thereofwith a segmental notch34,

`one wall 35, of which is curved, and the other of which is inclined, asseen at 36, for

purposes to appear more fully hereinafter. 0n the side of said disk '33,is`an abutment 37 arranged in a direct line with a stud 38, project-ingthrough a cam slotv 39, in said aforenamed disk 30. This. -stud issecured to the end of an arm 40, pivotally mounted jon the side of. saidcylinder 13. F ulcrumed in said casing by a pin 41, is a lever 42, whoseupper end is provided with a roller 43, arranged to slide over theperiphery of said disk 33, and out of said notch 34, and whose lower endis furnished with an elongated slot 44, in which the pin 45, of a link46, keyed on a rod 47, is arranged to operate. @n said rod are aplurality of niigers'48, for vremoving the developed paper from saidcylinder and delivering it tothe fixing bath in the following manner.

`When the disk 30, is oscillate'ol by the nut 31, in the direction ofthe arrow, Fig. 4, the cam slot 29, in the disk 30, causes t-he clampbar 19, to oscillate, and clamp the end of the 4' paper, as shown inFig. 5. Simultaneouslythepin 38, prjecting through the cam slot 39, isthrown outto a greater radius than. that in which the abutment 37 on thedlsky 33, lies, and consequently passes over the said der 13, in thedirectionof the arrow, Fig.

47, are in substantially the position. illustrated in Figs. 4, .5 andf6, and the roller 43,

. theme76 on the end of the lever 42, is inthe segmental notch 34, ofthe disk 33. When the periphery of the disk 33,`as shown in Fig.-

7. Such movement of the roller 43,l onto the periphery of the disk 33,causes the lever` 42, to operate the link 46, which, transmitting motionto the rod 47, carries the fingers 43,

into thel transverse grooves 49, in the cylinf yder-and under.thef'papenWhen saidroller 43, drops into the Inotch 34, of said disk 33,

' the lingers 48, now under the developed paper, gravitate totheposition shown in Figs. 4, aand 6, and in so doing, carry with them and,deliver the paper to the fixing bat-h.-

'llhe aforementioned curved wall 35, of said segmental notch 34, isprovided for the purpose'of preventing the pin 38, from revolving thedisk 33, in a direction opposite from` that indicated by the arrow inFig. 4, such curved wall 35, preventing the escape of said roller 43,from said notch 34.
